This invention relates to improvements in window construction,. andparticularly to windows of the sliding sash type.

One object of the present invention is to provide a construction andarrangement whereby the upper and lower sashes may be raised and loweredin the same manner as ordinary window sashes, and wherein theconstruction and .arrangement is such .as to enlU able either or both ofthe saslies to be tilted or swung inwardly topositions at variousdegrees of angularity with respect to the window casing or frame in amanner to provide A convenient access to the Aouter side of the windowglass for the purpose of lwashing or the like.

Another object of the invention is .to provide a novel construction andarrangement wherein the 'ordinary Vcoiinfterweights and sash chains orcords are employed for supporting the sashes in various ltiltedpositions of angularity with respect to the window frame in which thesashes are adjustably mounted. f l p Another object of the invention yisto provide novel and suitably positioned fulcrums around which the upperand lower sashes may be tilted, and supported by the sash chains atvarious angles with respect tothe '30 window frame.

Another object of the invention is to provide a novel form of metallicAweather stripping comprising a feature of the present invention, andparticularly adaptable for use in connection with-windows of thecharacter disclosed in the illustrative embodiment shown in thedrawings. p

A further object of the invention yis to provide a novel form of finger.or vbolt conguiding means, whereby the bolt may be convenientlymanipulated to various positions` and read-ily secured in such positionsin a manner to prevent accidental displacement therefrom. v

A. still further object of the invention is to improve devices ofthischaracter in sundry details hereinafter described and particularlypointed out in the appended claims.V A

Fig. l0 is a sectional plan view ofthe parts shown in Fig. 8, the viewbeing taken substantially as indicated by thev line 10-10 thereof.

In the illustrative embodiment .of the invention, a window Vframe orcasing, indicated as a whole by the numeral V11, is provided with upperand lower window sashes 12 and 13, respectively, to which are attachedone end of the vusual sash cords or chains 14 and l5 adapted to betrained over pulleys 16 and 17 rotatably mounted in outer and innerpulconnected and operable to counterbalance the upper sash 12, and thelatter, to counterbalance the lower sash 13. Y

For slidably mounting the sashes 12 and 13 in the frame 11, the pulleystiles 18 and 19 are provided with vertically disposed slots 22 and 23,respectively, and the sashes 12 and 13 are provided adjacent their loweredges with trunnions 24 and v25 adapted to vengage the slots 22 and 23of VtheV frame. Suitably positioned in the side fra-me members of theVsashes 12 and 13, adjacent the upper portions thereof, are bolts orlingers 26 slidably mounted in frame members 27 and adapted to beprojected into sliding engagement with the slots 22 and 23 asi'ndicatedby full lines in Figs. 3 and 5 and by dotted lines in Fig. 10. It willbe observed that by such an arrangement of the trunnions 24 and 25 andbolts 26 Ain the slots 22 and 23, thesashes 12 and 13 may be raised andlowered in the frame 11, as is customary in the ordinarywindow-construction, and that the engage- Y ment of the trunnions andbolts with the slots prevents any lateral movement of the sashes V,andconveniently accessible for 4adjustment therein.

It will beobserved by reference to Figs. 9 Y

and 10 that by turning the member 30 counterclockwise. the bolt andfinger grip meniber may be moved from the full line position to thedotted line position shown in Fig. 10, and by rotating the member inaclock- Vwise direct-ion, the shoulder 31 on the inember 30 will beforcedsnugly against the outer face of the frame member 2'? in a mannerto frictionally secure the bolt in adjusted position, either in or outof engagement with the slots 22 and 23 of the stiles 18 and 19.

This type of bolt construction is most desirable ina window structureor" the character described as it provides conveniently actuatedV meansfor positively securing the ,i 'bolts inoperative position inthe slotsin a manner to prevent accidental displacement v.therefrom and insureefficient operation ot' thedevice, j Y

Y For providing' convenient-n ,accessV tothe outer facevof thewindowsashes 12 and 13, the boltsn26 are withdrawn from engagement`withthe slotsV 22 and 23'andltheisashes lmoved,upwardly in the iframeor casing V11 until the VYtr-unnions 24 and 25 may be. posiitionedinnotches 32 and 33 formed adjacent to and communicating with the slots 22and 23, respectively, intermediate their end portions, thereby providingulcrums about which the sashes 12 and 13 may be tilted inwardly atvarious angles with respect to the r window frame 11, for example, tothe pesitions shown in Fig. 2, in which positions the upper or free endportions ot the sashes 12` and 13 are supported by means oi thesashchains 14 and 15, the sash weights .20,and 21 v serving tocounterbalance the weight ,of the sashes in their tilted or adjustedpositions.

ByV connecting the sash chains 14 and 15 t0 the side frame members ofthe sashes 12 and 13 intermediate their upper and lower end yportions ina manner to support the upper end portions of the sashes when in tiltedposition, suitable provision is made for permitting the tilting of thesashes about their fulcrums without interference by the sash chains, andfor this purpose the -outer longitudinal vertical edges of the sideframe niembers of the sashes 12 and 13 are cut away down to the point ofattachment of the sash chains 14 and 15, as indicated at 34 in Figs.

1, 3 and 5to provide ample space between the window trame 11 andadjacent portions of thev window sashes Jfor the passage or" the sashchains 14 and 15 as the sashes are swung inwardly to their tiltedpositions. v,

For suitably weather-stripping windows 'of the character described, thepulley stiles 18 and 19 are provided with wear plates V35, and betweenthel said plates and the stiles 18 andv19 are secured, by means ofscrews 36, the flanges or base portions 37 or" resilient metal weatherstrips 38, the yielding portions 390i which are adapted to be positionedbetween the outer `face of the lower sash 13 aiid the pulley stiles 18,and between the outer face of the upper sashV 12 and 4the weatherboard40. Thus, it will be observed that when the sashes 12 and 13 are intheir normal slidable position, as shown in Figs. 1, 3 and 5, the freeedges of the portions 39 oi the weather strips 38 will yieldingly engagethe outer faces of the sashes and provide a weathertight connectionbetween the frame 11 vand the sashes 12 and 13. l

Y It will be observed from the foregoing description that the presentinvention prei/'idee a novel type of window construction wherein thesashes 12 and 13 are slidablv and tiltably mounted, andY wherein thesash chains or cords 14 and 15 and counterweights 2O and 21 serve, notonly to support and counterbalance the weight of the sashes when intheir normal or slidable position, but also to support the sashes whentilted at vario-us angles with respect to the frame. Y Y Y VFurthermore,the present invention provides a novel type of weather strippingparticularly adaptable to windowv 4construction 'of the characterdescribed, and also anellicient and conveniently actuated bolt mechaniSmcapable of being secured in operative position and also out of operativeposition to prevent marring of the window frame in the event that thesashes, for any reason,

j, should be moved from their desired tilted position to a point wherethe counterweights would act to suddenly draw the window sashes intoalignment with the frame.

Obviously, the present invention is not limited to the preciseconstruction and arrangement shown and described, as .the same may bevariously modified. Moreover, all the features of the invention need notbe used conjointly as the same may be used to advantage in variouslydifferent combinations and sub-combinations.

What we claim is new and desire to secure by Letters Patentis:
